Scientists have concluded that about 3.5 million years ago, there was the first proto human. A proto human resembles extinct hominid populations that had some but not all the features of a modern homo sapien. Such features were prolonged moments of bipedality, change in the pelvis and the reduction of the sagittal crest. (Diamond 1992 pg 34) In order for this proto human to evolve into a human, it needed tools. Some of the tools might have been discovered by accident or by early creative geniuses? The way they discovered the tools is unknown, but the changes the tools made were to the physical morphology and the body behavior. They began to walk upright, gathered supplies, cut food, and used weapons.(Diamond 1992 pg. 40)

Not just hominids use tools. Wood-peckers, vultures and sea otters are among the other animal species that evolved by using tools to capture food, but these creatures are not as heavily dependant as we are.(Diamond 1992 pg 36) Without tools evolution might have taken much longer. Tools had a major affect on teeth, hair, behavior, and even language.(Diamond 1992 pg 12) When developing and using tools, the species takes control over the environment and makes it work for them.

In the movie 2001 Space Odyssey,(Anthropology 100 9/5/97) Stanley Kubrick gives his interpretation on how we evolve. The movie shows groups of stem-primate type creatures who represent early proto-human communities. The creatures begin to explore their environment finding resources and developing new ways to do things. The communities battled other primate communities for the natural resources in their environment. One of the primates begins to break some objects with a bone it picked up. The primate then realizes that this bone can do major damage. When one community learns to use bones as weapons, then that group can take over the resources in a certain area and be selected for, which increases reproductive fitness. This scenario could have happened but the truth is nobody knows exactly how and why things turned out the way they did.
